Desperate for extra speed, I tried jacking up my controller sensitivity from the default 0 to the max 7... and now I'm wondering why I didn't do it before

It only gained me a tenth off of my PB, but it made me a lot more consistent, so I could easily hit low 1:37's consistently whereas before I was averaging mid to high 1:37's. Being able to go full lock instantly just provides a lot more control in general. For example, as soon as I feel the back of the car beginning to slide out, I can neutralize it instantly with a tap of the stick, unlike before where there was a slight delay meaning I would catch the slide later losing more time.
I'll probably end up in D2 anyways though
